Also an opportunity to see what Kerkering looks like back-to-back.
But no way Lorenzen gets an AB IMO. Both he and the Phillies have been pretty clear about not doing it, it's an injury risk, and the focus should also be on what kind of pitching role they want for him (and then simulating that in 1-2 of these games).
If he's needed to PH or PR in the actual playoffs, sure, then you don't worry about the risk/distraction.
I'm sure Castro will play today but he doesn't really need to play to get ready for a post-season he'll never see. Let Cave and Sosa and Pache start every game. Stubbs too, sure, but more to rest JT (he also, ideally, won't get a single post-season AB again).
